摘      要：The acoustic velocity,attenuation,and their pressure dependence of a bulk metallic glass Zr_(41.2)Ti_(13.8)Cu_(12.5)Ni_(10.0)Be_(22.5) have been measured under pressures up to 0.5 GPa at room temperature using the pulse echo overlap *** sample was prepared from melt by quenching into liquid *** modulus,Young’s modulus,shear modulus,and Poisson’s ratio were derived,other elastic properties and vibrational anharmonicity were also discussed.
